Having returned with his new single Love U, it has taken Seo In Kook just three weeks to grab his first #1. Since returning on May 6th with his new single, Seo In Kook has been achieving success on charts. After losing out to 2PM who claimed their triple crown last week, Seo In Kook fought back to even the score this evening as he claimed his first-ever No.1 trophy since debuting as a singer on the May 20th episode of M! Countdown. http://www.youtube.com/watch?v=spQLos3IcAo Congratulations to the Super Star K winner who adds another trophy to his cabinet!
